How would I be able to write a function that checks a tuple if it contains at least 2 `H`

elements in the list. So for the example below there are 2 tuples in `A`

that contain 2 `H`

elements `{('H', 'H', 'H', 'T') and ('T', 'H', 'H', 'T')}`

?

```
A = [('H', 'H', 'H', 'T'), ('T', 'T', 'T', 'T'), ('T', 'H', 'H', 'T'), ('T', 'T', 'T', 'H'),]
```

### >Solution :

Use the `tuple.count()`

method to count the number of `H`

elements. Then you can use `sum()`

to total the number of times this is at least 2.

```
A = [('H', 'H', 'H', 'T'), ('T', 'T', 'T', 'T'), ('T', 'H', 'H', 'T'), ('T', 'T', 'T', 'H'),]
num_2H = sum(item.count('H') >= 2 for item in A)
print(num_2H) # prints 2
```
